Ulysse Nardin Marine Torpilleur Tourbillon

Ulysse Nardin's Marine Torpilleur Tourbillon, reference 1283-310-0AE/1A, comes in a 42 mm steel case. The case measures 11.93 mm thick. A sapphire crystal covers the white enamel dial. Inside is the self-winding calibre UN-128 Constant, with a flying tourbillon and a silicon escapement, offering 60 hours of power reserve. The dial displays this reserve alongside the hours and minutes, and the tourbillon sits visible through the dial side. An alligator leather strap completes the piece. Water resistance is rated to 50 metres, modest for a watch built around such a technical movement.
